Aretha Franklin and Smokey Robinson, 'Ooo Baby Baby' (1979)

Aretha Franklin and Smokey Robinson sat at a piano together, talking about knowing each other when they grew up on the north side of Detroit and harmonizing on a heavenly duet of the Miracles' "Ooo Baby Baby." (Although they made a big deal of their age difference here, Robinson was only two years older than Franklin – they were 39 and 37 when this was filmed.)
